WI-IIFFLETREE-I-IOOK.

Application led April 17,

To all wh-m t may concern.'

Be it known that I, GEORGE I-I. ROBERTS,

a citizen of the United States, residing at Thomas, in the county ofCuster and State of Oklahoma, have invented certain new and usefulImprovements in IVhiHietreoHooks, of which the following is aspecication, reference being had` to the accompanying drawings.

This invention relates to new and useful improvements in -whiliietreehooks, t-he object of the invention being to provide a hook of thischaracter which is adapted to securely hold the trace upon the end ofthe f swinglet'ree and prevent the trace from becoming accidentallyunhooked from the end of the swingletree.

Another object of the invention is to provide a device of this characterwhich will possess advantages in points of efficiency and durability, isinexpensive of manufacture and at the same time is simple inconstruction and operation.

Vtith the above and other objects in view the invention consists in thenovel features of construction and the combination and arrangement ofparts hereinafter more fully described, pointed out in the claims andshown in the accompanying drawings in which,

Figure 1 is an elevation of one end o-f a swingletree showing myimproved hook applied thereto. Fig. 2 is a sectional view on the line2-2 of Fig. 1. Fig. 3 is a detailed perspective view of the retainingmember.

Referring more particularly to the drawings, 1 indicates a metallicferrule adapted to be applied to the end of the whifietree 2. Centrallyarranged in the closed end of the ferrule is the screw 3 adapted to bescrewed into the end of the whiiiietree to hold the ferrule securely inplace, the outer end of the screw being formed. smooth and extends outbeyond the end of the ferru'le and over .which the-end of the trace 4lis adapted to be hooked.

' Formed on the ferrule and arranged at diametrically opposite pointsare the outwardly extending lugs 5 and 6. Pivotally secured to the lug 5by means of the rivet 7 is the angular 'bar 8 having the openingSpecication of Letters Patent.

9 formed therein, which, when the bar is swung to a closed position isadapted to receive the outer end of the screw 3. Secured to the free endof the bar 8 by means of the rivet 10 1s the spring plate l1, said platebeing provided adjacent its free end with the spaced ribs l2 which areadapted to engage upon each side of the lug 6 to hold the bar 8 securelyupon the outer end of the screw 3 and prevent the trace 4l from becomingaccidentally unhooked from the end of the swingletree.

In the operation of the device, the trace 4L is first hooked over theouter end of the screw 3 and the bar 8 is swung across the end of theswingletree, the outer end of the screw engaging the opening 9, and theribs 12 engaging with the lug 6 to hold the bar securely in place. Itwill be seen that the free end of the plate 11 is curved slightly asshown at 18 so that the same can be easily grasped to release the ribs12 from the lug 6 when the trace is to be unhooked from the swingletree.4

While I have shown and described the preferred form of my invention itwill be obvious that variousA changes in the details of construction andin the proportions may be resorted to for successfully carrying myinvention into practice without sacrificing any of the novel features ordeparting from the scope thereof.

What I claim is 1. In a device of the character described, thecombination with a swingletree, of a fer rule rigidly secured to the endthereof, lugs formed on t-he ferrule at diametrically op posite points,an angular bar pivotally secured to one of said lugs and having one ofits ends disposed across the end of the swingletree, a spring platerigidly secured to the free end of said bar, spaced ribs formed on theouter end of the plate and adapted to engage with one of said lugs tohold the bar in an operative position, and means projecting from the endof the swingletree to retain the trace in position between said bar andthe swingletree.

2. In a device of the character described, the combination with aswingletree, of a fer* rule, a screw centrally arranged therein, havingits threaded end screwed into the end of the swingletree and the otherend eXtendto engage the other lug to hold the bar in ing beyond theclosed end of the errule, an operative position. 10 lugs formed on theferrule at diametrieaily In testimony whereof I hereunto aix my oppositepoints, an angular bar pvotallysesignature in the presence of twowitnesses.

cured to one of said lugs, said bar having GEORGE H. ROBERTS. en openingformed therein to receive the Witnesses:
